Dow down 416 pts! - Why?

The reason that the Dow Jones went down because the chinese that make the goods for certain company in the Dow Jones. The chinese market went down 9% and everybody knew once they went down the U.S Market was going to go down because we have alot invested in the Chinese market.This compares to the great dpression and 9-11 because they both have major decreases in the stock market because those were bad times for the us but in this instinct it was bad time for another conutries market that we have so much invested in with that certain country. No it not a good time to buy because the stock market down and you could lose alot of money if the stock market does not go uup in a week you would of lost alot of money by this time
